Behind Closed Doors

Basically in the early 2000's, the official SpongeBob storyboard artists actually made "questionable drawings" in a secret book titled "Behind Closed Doors" they made.

It was lost for 20 years & became forgotten, until someone uploaded it onto Archive.org for everyone to share. Now you might be thinking, what is "Behind Closed Doors" anyways?

Well remember that rumor where SpongeBob would be getting an adult party cartoon?

Well it's basically that in storyboard form & yes that means Nickelodeon/Viacom canonally owns 18+ SpongeBob stuff, I have no words except WHAT THE HELL WERE THE STORYBOARD DIRECTORS ACTUALLY THINKING WHILE MAKING THAT?!

Also remember those "images" hidden in SuperSponge's files? My theory is that their origin was based on a few storyboard segments from Behind Closed Doors.

It could be possibly on why the developers of SuperSponge have putted those cursed images in the files in the 1st place, as Nickelodeon gave the team working on SuperSponge the official character sketches as a reference during development.

LSuperSonicQ has covered this already & thankfully he censors the images in said video, so I recommend watching for more info about this & how this is officially canon in the SpongeBob Universe now (if you want to see the uncensored images of these, search it up yourself ok?):
